PATENT OFFICE LOADER. ANCHORAGE FOR RAILWAY GARS William D. Thompson, Birmingham, Mich., assignor, by mesneassignments, to Standard Railway Equipment Manufacturing Company, a corporation of Delaware 'Application April20, 1936, Serial No. 75,472 '2 Claims; (01.105-404) The invention relates to apparatus for loading andjunloading' railway. cars. In the present state of the 'art it is usual to anchor such loading apparatus to the roof of the car. Thisplaces additional stresses inthe structural elements of the roof and necessitates certain modifications in design to take careof such stresses. It is the objectof the present invention to provide an anchorage for the loader which is entirely independent of the roof structure but which is nevertheless so arranged as to provide at least equal clearance in the car. To this end the invention consists in the construction as hereinafter Inthe drawings: a

Fig. 1' is a cross section through a portion of a railway oar'jto which my improvements are applied;

" jCar roofs are usually supported on a roof frame comprising carlines and purlines, but with certain constructions this frame is dispensed with and the weatherproofing sheets are fashioned'to I also sustain the load. My improved lroist anchorage is applied to a roof'of the latter type, and as shown this comprises alternate upper and lower plane panels A and B connected by substantially vertical portions C and extending from cave" to eave; At the eaves both upper and lower plane portions merge into a downturned portion D which is arranged in a common plane and is connected to the side plates E of the car frame. My improved loader anchorage or support comprises a pair of beams F which extend 0 across the car and at their opposite ends are connected to and. supported by the side plates E. These beams may be of any suitable cross sectional contour but as shown are inverted channel beams with laterally extending base flanges G.

The beams are also fashioned so that for a portion of their length they conform substantially to the pitch of the roof and are located in the space provided beneath one of the upper plane panels A. This brings the flanges G only a slight distance below the plane of the lower panel B and permits of supporting a truss H on the flanges of the two beams so as to extend beneath the lower plane in close proximity thereto. This truss forms a part of the loader apparatus which is not the subject matter of this invention, but the 'g.3 is'a' view similar to a portion of 1 construction and arrangement of the beams F is such as to provide support for the truss and to carry the entire load independent of the roof. At the same time the construction of the roof having upper and lower plane portions permits of placing the beams chiefly within the vertical dimension of the roof without cutting down on clearance within the car. The central portion F of thel beam F need not conform to the pitch of the roof, but may be dropped below the same, as there isabundant clearance at this point.

With certain constructions of cars to which the loader anchorage is applied, the side plates E are not provided with a laterally inwardly extending flange to which the beams F can be secured. I I may, therefore, employ the construction shown in Figure 3 in which an angle bracket I is secured to the vertical flange of the carline E between the same and the downtumed flange of the roof. This angle bracket is secured to the'end' of the beam and forms the connection between the same and the side plate.

In Figure 4, I have shown a construction where the beams F are completely within the space between the upper and lower planes of. the roof, and the truss H has its ends ofiset upwardly for engagement with the flanges of said beams.

One important advantage of the loader construction as above described is that it does not modify or interfere in any way with the functioning of the roof. Thus,.as illustrated in the drawin'gs", and particularly in Figures 1 and 2,,v the beams F aresufficiently spaced from the upper panels of the roof to be at all times out of stress communicating contact therewith. Also, the loader beam H while in proximity to the lower panel is spaced therefrom sufliciently to be out of stress communicating contact. As a consequence, the roof when subjected to stresses incident to the normal use of the car remains clear of the loader, so that the presence of the latter is in no way detrimental.

What I claim as my invention is:

1. In a car comprising side plates, and a roof having upper and lower plane panels extending across between said side plates and secured thereto said panels and connecting intermediate portions forming the sole roof supporting trusses, a loader support comprising a beam independent of and out of contact with said roof supported at its opposite ends on said side plates and extending across the car, a portion of said beam being within the space beneath an upper panel and between the same and the plane of the lower panel of' the roof said beam being at all times out of stress communicating contact with said roof.

2. In a car comprising side plates, and a roof having upper and lower plane panels extending 5 between said side plates and secured thereto said panels and connecting intermediate portions forming the sole roof supporting trusses, a loader support comprising a beam independent 01 and out of contact with said roof supported at its opposite ends on said side plates and extending across the car, a portion of the length of said beam being located within the space beneath an upper panel and between the same and the plane of the lower panel of the roof and said beam having a laterally extending flange at the side of this portion located a slight distance below the plane of a lower panel of the roof said beam being at all times out of stress communicating contact with said roof.

3. In a car comprising side plates, and a roof having upper and lower plane panels extending between said side plates and secured thereto said panels and connecting intermediate portions forming the sole roof supporting trusses, a loader 25 support comprising a pair of beams independent 5 of and out of contact with said roof supported at their opposite ends on the side plates and extending across the car beneath upper plane panels thereof, at least a portion of the length 01. so each beam being located largely within the space ,,jbeneath said upper panels and between the same and the plane of the lower panel being always out of stress communicating contact with the roof and having a laterally extending flange at 35 one side thereof arranged slightly below the plane of the lower panel of the roof, said laterally extending flanges providing support for opposite ends of a truss extending between said beams and arranged just below the lower plane panel. 40 4. In a car comprising side plates, and a roof :;haVing upper and lower plane panels extending between said side plates and secured thereto said panels and connecting intermediate portions forming the sole roof supporting trusses, a loader 45 support comprising a pair of beams of inverted tgchannel cross section having a laterally extending side flange, said beams extending between and having their opposite ends supported upon said side plates and being located beneath upper 50 plane panels of the roof and independent thereof .nand out of contact therewith, at least a portion of the length of said beam being arranged large- 1y within the space beneath an upper panel and between the same and the plane of the lower panel being always out oi stress communicating contact with the root and with the laterally extending flange located slightly below the plane of the lower panel, said flanges providing a support for opposite ends of a truss extending between said beams.

5. In a car comprising side plates, and a roof having upper and lower plane panels extending between said side plates and secured thereto said panels and connecting intermediate portions forming the sole roof supporting trusses, of a loader support extending within the space beneath an upper panel and between the same and the plane of the lower panel of the roof but independent of and out of contact with said root at all times.

6. In a car comprising side plates, and a roof having upper and lower plane panels extending between said side plates and secured thereto said panels and connecting intermediate portions forming the sole roof supporting trusses, a loader support comprising a pair of beams extending between and having their opposite ends supported upon said side plates, said beams being independent of and out of contact with said roof located beneath the upper plane panels thereof and largely within the space between the same and the plane of the lower panels being always out of stress communicating contact with the roof, and a truss having its opposite end secured to said beams and extending therebetween beneath the lower plane panel whereby the load stresses are carried into a plurality of beams.

'7. In a car comprising side plates, and a roof having upper and lower plane panels extending between said side plates and secured thereto, said panels and connecting intermediate portions forming the sole roof supporting trusses, a loader support comprising a pair of beams independent of and out of contact with said roof, said beams being supported at their opposite endson the side plates and extending across the car beneath the upper plane panels thereof at least a portion of the length of each beam being located within the space beneath said upper panels between the same and the plane of the lower panels being always out of stress communicating contact with the roof, and a truss extending between and having its opposite ends supported upon said beams, said truss being arranged just below the lower plane panel and at all times out of stress communicating contact therewith,
